The connection from your weather component (Type15) to your
psychrometrics component (Type33) includes the humidity ratio but no
atmospheric pressure or temperature. Consequently, Type33 is trying
to calculate thermodynamic moist air properties for a varying
humidity ratio at a constant 20C and 1atm. Very often the result
that it comes up with is above the saturation line. I think if you
connect the ambient temperature and pressure to Type33 your errors
will go away.<br>

<pre wrap="">Hi, I have a question using energy plus weather file with type 56. I am currently dealing with simulation of simple "black box" building located in humid, hot climate (Singapore). I downloaed the data from Energy + site and result of simulation should be condensation in the building....I have problem with running the simulation, it causes errors all the time. Can you help?
Thanks, Marek
